The sheriff's office had two locksmiths come, but they could not open the door.

“The door was barricaded after we got the locks open,” said John Firestine, a locksmith.

Deputies knocked down the door with a battering ram, and that's when the man came out and started shooting.

“He was aiming at whoever was at the door,” said Mark Randall, a locksmith.

“The bullets whizzed by me,” said Firestine.

Deputies fired back at the man, ultimately killing him.

“I was turning and going already, and that's when he shot. They had to return fire and killed him,” said Firestine.

The man has not been identified.

Lincoln police are now handling the criminal investigation. They said the bank evicted the man about a month ago.

“He came back to the residence and was living in the residence,” said Chief Jim Peschong.

Police were at the house two weeks ago telling the man to leave. Officers did not remove him at that time but suggested he go to the bank to go through the eviction process again.

The sheriff's office will conduct an internal investigation to determine whether all procedures were followed. State law requires a citizens grand jury be convened anytime there is an officer-involved death.
